How it works
It all starts with a consultation. Your surgeon will ask about your cancer history, any radiation or chemotherapy you have had, your past surgeries, and what you hope your shape will look like. They will examine your chest and your belly to see whether you have enough tissue and suitable blood vessels, and then talk with you about whether to reconstruct during the mastectomy itself or to wait and do it later (a second stage).
The surgery is done under general anesthesia, which means you are fully asleep and feel nothing during the operation. Your surgeon removes an oval piece of skin and fat from your lower belly, usually together with the blood vessels that feed that area. Depending on the technique, the surgeon may keep the flap attached to its original blood vessels and tunnel it up to the chest, or detach it and reconnect tiny blood vessels under a microscope (microsurgery).
Once the tissue is in place, the surgeon shapes the breast to balance with the other side, closes the chest incision, and repairs the abdominal wall. The belly incision runs low and across, similar to a tummy-tuck line, and the surgeon usually rebuilds the navel. The nipple and areola, if you want them, are usually rebuilt in a smaller procedure weeks or months later.
In the first days after surgery, the team watches the color and warmth of the flap closely to make sure its blood supply is good. This is the most important part of your hospital stay, because a healthy flap is the foundation for a lasting result.
